Fuel and Ventilation Controlled Fires
© Springer Science+Business Media New York 2015 H. Ingason et al., Tunnel Fire Dynamics, DOI 10.1007/978-1-4939-2199-7_2 Abstract The effect of ventilation on fire development is one of the most important phenomena to understand in tunnel fire safety engineering. Ventilation controls the combustion process and is usually the phenomenon that engineers find most difficult to comprehend. Tunnel fi...
متن کاملFires in Tunnels: Experiments and Modelling
The development of fire safety research in road tunnels during the past 20 years is reviewed, with particular reference to the activity of the Flame Research Group at Politecnico di Torino (Italy). Simulations of fire accidents in tunnels are described for both full-scale tests in real tunnels and for laboratory-scale tests. It is shown how simple semiempirical thermo-fluid dynamic models are a...
متن کاملThe critical ventilation velocity in tunnel fires—a computer simulation
In ventilated tunnel fires, smoke and hot combustion products may form a layer near the ceiling and flow in the direction opposite to the ventilation stream. The existence of this reverse stratified flow has an important bearing on fire fighting and evacuation of underground mine roadways, tunnels and building corridors. In the present study, conducted by the National Institute for Occupational...
متن کاملA New Approach to Ventilation Measurements in Enclosure Fires
The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. Stereoscopic PIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in a flow. The technique is completely independent of temperature and differential pressure measurements typically applied to quantify ventilati...
متن کاملModelling Aspects of Sprinkler Spray Dynamics in Fires
S prinklers are used extensively in a variety of fire protection applications. These systems are required to perform effectively over a wide range of extremely harsh and complex operating conditions. The sprinkler performance depends on the initiation, formation, dispersion and surface cooling characteristics of the sprays created by these devices. The behaviour of sprinkler sprays is strongly ...
